Being able to pick your own champions!
We save 4 * and 5* shards to be able to gain new champions, then feel like a fool when you pull she hulk or iron patriot, kabam why don't you let players pick their own 4+5*champs?
I have 10 unduped 5* and I know I'm not on my own, and my most recently introduced character is Quake!! IF I COLLECT THE SHARDS LET ME PICK THE REWARDS.
